Interpretive Summary: This review article will focus on multiple aspects of Streptococcus iniae and S. agalactiae pathogens in warm-water fish including global distribution, fish species affected, disease signs, sample collection, transport and storage for successful survival and isolation of the bacteria, identification of bacteria by conventional, automated and molecular diagnostic techniques, antibiotic sensitivities, environmental influences on disease outbreaks and immunity and vaccinology. Overall, this article will chronicle the road from emergence of these piscine pathogens to detection, understanding, treatment and prevention

Technical Abstract: Despite being known mainly as mammalian disease agents, Streptococcus iniae and S. agalactiae have become recognized as emerging pathogens of wild and cultured fish. The worldwide economic impact of S. iniae and S. agalactiae to the aquaculture industry is estimated in hundreds of millions annually. This review article will focus on the epizootiological aspects of these pathogens in tilapia Oreochromis spp. and other warm-water fish including global distribution, fish hosts susceptibility, disease signs, sample collection, transport and storage for successful survival and isolation, identification by conventional, automated and molecular diagnostic techniques, antibiotic sensitivities, environmental influences on disease susceptibility and immunity and vaccinology. Overall, this review will chronicle the road from emergence of these piscine pathogens to detection, understanding, treatment and prevention.
